Unbelievable calculator! Simple, yet very flexible. Well worth the little price...... Would love to see some type of data tracking incorporated so that I don't have to use a separate application for my data reports (merge this and OnTrack Diabetes and it would be the excellent product!)

Who has a application (that's doesn't work), so then you have to $0.99 for another "version"of the application that should just be since it doesn't do anything, then asks to another $4.99 for the "full version"? Fix this and maybe you wouldn't have such low ratings! I better obtain my back!

I use this application regularly and it's very helpful calculating correct exposure. Only negative is I [email protected]#$%! some times not available in the application but I create a guess and experiment

The application is amazing so far, however the input for the horizontal destination measurement does not work. Therefore, either I have to enter information assuming there is either no horizontal motion, or the employee is lifting an object toward themselves, which is not helpful. Please fix this bug, and the application will be that much more useful.

Almost perfect, but this is true globe and true software, which is not bug-free. When filling up the distance, when I switch to e.g. calculator, the distance I place in is being changed to some random (other memory cell's?) value. Other than that, it is really good. Just bought a premium ver because I use it since over a year and I think it totally deserves my cash.

Improved layout. 👍 Original feedback: I play on smartphone and most of the screen is just empty and I'd rather have bigger buttons because when I test to play really quick, sometimes I miss the key I wish to hit, thus getting poor results unnecessarily. Maybe just having buttons twice their height would help. Also, the text (equation) is far from the buttons and that makes it even harder to play because eyes have to move up and down all the time, thus slowing me down. Please reconsider.

This is a small, fast and usable app. There are 2 suggestions I would create to the author for improvement based on my expertise in Human Factors Engineering and Human Reliability Analysis. 1. As photographers we all work in stops and the application does present stops for all filter factors. However, there are 2 ways ND filters are specified by filter factors of 0.3, 0.6, 0.9, 1.2, etc. which equates to 1, 2, 3, and 4 stops of exposure reduction. Some manufacturers specify their filters with a filter fact such as ND 2, ND4, ND8, ND16, ND32, etc. which equates to 1, 2, 3, 4 and 5 stops. It would be helpful for some to have this filter factor specified in addition or as an option that could be set. 2. The other problem is more fundamental. The application shows a scrolling list of filter factors side by side with a scrolling list of shutter speeds. My initial assumption was that you lined up the shutter speed with the filter factor and it would give the answer. However, what you actually do is tap the filter factor and tap the shutter speed. Unfortunately, the application doesn't present you which filter factor or shutter speed is selected in the list.

Ivehad this application and the previous versions and im finding the presentation of the results difficult to read. The older ver was much better presentation wise. Byt this is a amazing and useful application

There is 2 times "6 stops" in the left column and the calculation is not always accurate. For example if I begin with 1/1000 sec., for 7 Stops I obtain 1/4" that is okay, but for 8 Stops I obtain 0"4" (???) , for 9 Stops I obtain 0"5" (???).

I'm using this application from a while and it was , if you wish to add a fresh refuel, the GPS is activated automatically, which I dont wish to use, and the battery is used a lot in the mean time. Please create possible to swich it on or off. Till than, I wish to return to the ver 3.6? How?
